or seasoning which is usually applied to the.

grain side of the skin.

According to my invention the skin which is to be treated is carried around the under side of a rotating drum, being held in place thereon by a series of cords. As the drum rotates, carrying the skin, a succession of cylindrical brushes apply a liquid to the skin or brush liquid thus applied into the skin, as will be hereinafter more particularly described.

In the accompanying drawings, Figure I, is a front elevation of a machine emhodying my -invention. Fig. H, is a rear elevation of the same. Figs. 1H and IV, are the two end elevations of the machine. Fig. V, is a section along the line V, V, of Fig. 1. Figs. VI to IX inclusive, are detailed views of the scraper mechanism. Fig. X, is a detail showing the method of adjusting certain of the brush rollers with respect to the supporting drum; for the skins. Fig. X1, is a detail of the strainer in the liquid receptacle. Fig. XII, is a detail cross section through the seasoning liquid supply pan, showing the adjustable overflow pipe therefor; and Fig. XIII, is a modified form of slack take up for the retainer cords which hold the skin in contact with the supporting drum (hiring their passage through the machine.

Referring to Fig. V, the drum 1, which is preferably a large metal cylinder, mounted -on spider frames 2, rotates in the direction of the arrow. A series of endless cords or wires 3, pass around the grooved roller 4, and thence against the lower and rear surface of the drum, moving in the same direction, and at the same ratevas the drum, until they reach the grooved roller 5, around which they pass and thence descend and return to the grooved roller 4, after passing around the guide rollers 6 and '2'. The

A tension with its weight against th s and maintains pressure to siou of the cords against tli drum, and keep them under a constant c. yielding tension as they pass around under it. This tension roller 9, is mounted on arms 10, 10, swinging upon the shaft 11.

'l'hc application roller 13, which is pref erahly a cylindrical brush, rotates in the direction of the arrow. T he lower part of this roller is sulunerged within the liquid con- 'tained in the pan 1%, while the upper part of the roller comes in contact'with the surface of the skin passing around the drum and applies the liquid to its surface, notwithstanding the intervening cords, which are relatively small interfere very slightly with the even application of the liquid. "The brush roller 15, as in (heated by the arrow, to ...oroughly is given an oscillatory motion as it rotates. This oscillatory motion enables the brush to disseminate the liquid beneath. the portions of the skin underlying the cords, which are by the oscillation of the brush rolled slightly to one side or, the other. The movement of this brush in the opposite direction from that of the brush 1?, serves the further useful function of applying the liquid toall parts of horizontal fold if the same shall. point, and upon which the previous brushes rotating in the opposite direction may have applied the liquid only to one side.

The brush roller 20, rotztcs as indicated by the arrow and coiiigizletes the thorough application of the liquid t all its of the skin operating upon it after .ias left the cords so that all parts of the surface of the an oscillating cam.

The drum 1, is mounted on a shaft 40,"-

which is journaled in bearings 41, '41, formed at the top ofjhe side frames 36, 36,

provided with a spur gear 42, which is driven from a pinion 43, on the stub,

shaft 39.

The cords or wires 3, are positively driven from the grooved rollers 4, and 5, which are connected by a, sprocket chain. 45, as best seen in Fig. IV. The shaft 46, upon which roller 5, is mounted, carries at its other end (Fig. III) a sprocket 47, which is driven by means of a chain 48, from a sprocket 49,, .also mounted upon the stub shaft 39.

Brush, 16, is driven directly from the pulley shaft 32,by means- 'of a chain 57, (see Fig. III) and the shaft upon which this brush is mounted, inturn drives the brush 15, by means of a chain 58,

see -Fig. 1V. Brush 20, is driven by means i achain 59, from a sprocket 69, also carried by the stub shaft 39, as best, seen in Fig, III. At the opposite cndof the machine (Fig. IV) the shaft 61, upon which brush 20, is mounted, carries a sprocket 62, which through a chain 63, drives the brush roller 17. By this system of. driving the the foam which tends to'j 'fOllIlDIlliliQ} surfaceof the liquid in the res- .ervoir, from' being' drawn into the pump. In order-to prevent'everfiowing of the pan.

passes around the drum.

Feedingbrush 13, is supported by arms 65, 65, loo'sely'mounted adjacent the side frame; '36, on the shaft 54-, which carries the cord driving roller 4. Thesearms'are l adjustably suspended fromfthe frames 36, respect vely. ThlS shaft is ournaledme standard 35, and also in the side frames 36,

36, by means of rods 66, which are threaded and secured to brackets 67. By the manipulation ofnuts 68, on rods 66, the brush 13,

.may be readily adjusted with respect tot-he drum 1. Brush 15, is similarly suspended *in arms '69, from shaft32, and may be likewise adjusted with respect to the drum 1, by Tmeans of a threaded rod 70. Brushes 16, 17

and 20, are mounted in adjustable bearin s, each /'cornprehensively indicated at 1 1.

-'These'bearings are all similar invco-nstruction and for convenience one of the bearings for roll 20, has been chosen for illustration in detaii in Fig. X. It will, of course, be understobd that. this description will hold good for allof them. In this figure the bearing 71, is slidably mounted upon the standard '36, by means of bolts 72," which pass through slots 73, in the frame. The bearing is supplementedby a boss 7 5. which is internally threaded and engaged by a screw thread formed on the inner end of a stub shaft 7 6, which carries a bevel. pinion THE Cir

is absolutely clean. This is very from the drum 1, as circumstances may require. The bearings 71, 71, for the roll 20,

are adapted to be simultaneously adjusted by means of a hand wheel 78, which is mounted on a shaft 79 (see Fig. ll), having bevel pmions 80, which mesh with the bevel 'pinions 77, already described.

side frames 36. The brushes may bythis means be retracted from the drum 1, and again returned to their active positions, without destroying the original adjustment. On the main figures of the drawings these stop screws 81, have been illustrated only in connection with the brush 20, it being, of course, understood that each of the brushes of the group ust described i s, in actual practice, supplemented with the screws.

In front of the machine is mounted a table 83, by which the skin is guided. as it 1 is passed down between the drum and the cords. There is alsoprovided a transverse scraper 85. This scraper is illustrated in detail in Figs. V1 to IX inclusive. It is preferably formed of hard rubber and supported by a plate which extends practically the full width of the machine and is adjustably mounted (as will be explained later) upon inclined eXtei ions 87, projecting from the side frames 68. The scraper is provided with a metallic backing strip 88, and these are together adjustably held between the plate 8-6, and a guiding plate 89, secured to the spacing ridge 90, formed" on plate 86. The adjustment of scraper 85, is accomplishedby means of a series of set screws 91, which are threaded into the ridge 90, and engage the backing strip 88, for the scraper. adjustment is essential for Wear compensation and. for maintaining close contact of the th surface of the drum, so that portion of the drum presented at the feeding point important in that the value of the finished; product is greatly decreased when stained flesh s' l in cider to prevent the scraper from sticking to the drum during the idle periods of the machine, for the same reason as already pointed out in connection with the several brushes, the plate 86, is so mounted These screws are roller 100.

with respect to upon the i upon its supports 87, as to be capable of being retracted with respect to the drum 1. This is accomplished by means of eccentrics 92, one at each side of the machine. These eccentrics are mounted for rotation in the extensions'87, and engage squared apertures 93, (Fig. IX) on the ends of the plate 86, and are actuated through the instrumentality of hand levers 95. Plate 86, is guided in its'lateral motion by means oi stud bolts 96, which are secured in the extension 87, and pass through slots 97, in the said plate. It will be readily seen that a. half rotation of the eccentrics 92, will sufiice to retract the scraper from contact with the drum during the idle periods of the machine. Here again the construction of the parts just described is such as to permit the retraction and return of the scraper Without destroying the original adjustment of the scraper by means of screws 91.. .The liquid scraped from the drum collects n the gutter formed by the angle of inclination of the scraper with respect to the drum, and drips off the ends into the splash pan 22. Conduits may be provided to direct the liquid from the ends of this gutter but no attempt has been made to illustrate these, in order to avoid complicating the drawings.

In Fig". XIII, I have illustrated a modified means for maintaining the proper tension 'on the cords 8. In. this modification each cord is provided with a. grooved tension This roller is mounted in an arm 101, pivotally attached to a lug 102, secured to an angle iron 103, adapted to extend the full Width of the machine and to be attached to the side frames 36. The arm 101, is slightly overbalanced at the'roller end, so that gravity will at all times hold the roller in engagement with its cord and thereby compensate for the slack. By use of this modification the slack of each cord may be taken up individually since as before stated, there is one of these rollers for each cord.

In operation the skins are fed by hand over the table 83, and carried by the continuous movementot' the drum and gears down and around the drum into successive contact with the brushes, the grain surface of the skin being always exposed to such brushes. The cords hold the skin evenly and flatly against the drum, preventing the wrinklingor kinking thereof, and preventing the edges of the skin from turning over and the shanks of the skin from kicking up. This device combined with the application of theseasonin; liquid to the under side of the skin prevents the unintentional and objectionable application of liquid to the flesh side of the skin, as occurs in other varieties of machinery intended for the same purpose. As the skin passes around the .cll.

drum the seasoning liquid is applied to it by the brush 13, any surplus liquid dripping oil into the pan, or being brushed elf successively ey the brushes lo'and 16, which further assist'the working of the liquid into the skin. The amount of liquid taken up by the brush is carefully regulated by adjusting the overflow pipe in relation to the pan. As the skin progresses it meets the os llating brush 1?, by which the cords are sullicieutly vibrated to work the liquid against the underlying parts of the skin and any horizontal kinks turned over the same, the san e function being still further performed by the roller 20, after passing which, the skin is removed by the operator from the drum, as it is passing over the top thereof,

and a new skin a plied.
